Super Slim and Ruggedized Vehicle Relay Module

VTK-RELAY is a super slim, ruggedized RELAY module. It is remotely controlled through an on board MCU and transmitted via RS-232 or USB 2.0 communication. With 4 x relay output, 4 x DI, 4 x DO, 1 x analog input, and 1 x frequency input for customer easily to setup vehicle system. It allows to comply with stringent MIL-STD-810G military standard in rugged, compact mechanism. Because of the super slim design, it is especially for the vehicles with limited space to control the system, but without compromising with its space to scarify its features. VTK-RELAY contains no DIP switches, by merely issuing a command from the vehicle computer, you can change RELAY/DI/DO setting to reach your application.
